We always need a good way to keep track of Family Home Evening assignments! We made these tiles at our RS Super Saturday a few years back. The scrapbook paper is modge podged over a piece of sheet metal - so it's magnetic. We didn't modge podge over the paper though because we weren't sure how magnetic it would be through the modge podge.
The magnets are made by cutting your faces out of a photo (circle punch works great!). They are then glued on the back of those clear little buttons (like half a marble) with a clear silicone glue. And then the magnet is glued on the back as well. You could also print names instead of pictures. Works great and is so easy for changing assignments. And when a child leaves home, they can take their magnet with them!!!
